The scenario above uses the logic you're using to defend oorah+merge is asymmetrically balance with the LMG upgrade. It just isn't and although the example I've given is extremely exaggerated the logic used is still the same with yours.
Yes, Im glad you recognise it is an extreme example. So extreme, that it infact becomes ridiculous because you have amplified only those elements which suit you, while neglecting to realise the same logic actually refutes your point in the first place.
First of all, in the previous xomment you had already said you dont give a shit about other units, or comparative balance, you just want a buff. But then you go on to present a contrived example that is comparative.
Second of all, though you make it clear this is about backbone infantry, you make your example be about builders for some inexplicable reason.
Third of all, you create an example that would have absolutely gamebreaking results.
Fourth of all, you use abilities only in your example, not actually weapon upgrades. Though the point was about both.
Fifth of all, you present that the "50 abilities" dont exactly give you a serious advantage, presenting that as is Oorah or Merge neither are a serious advantage.
In total, this results in what is known as argumentum ad absurdum.

Anyways, back to topic:
Yes, I get what you want.
You want everything Cons already have AND a weapons upgrade ontop of that.
Regardless of the fact no other backbone unit has anything evennremotely similar to the 2 native abilities from the get go that Cons do, and instead rely on a weapons upgrade, solely, to scale.
You seem to completely disregard Oorah and Merge as anything of value, or consideration, yet at the same time, in contradiction, you still want to hold onto them, therefore actually ascribing them value, because youndo infact want to keep them AS WELL as having the weapons upgrade which is the sole scaling option available tonother units which simply dont have native abilities with this kind of utility likenthis right out of the box.
If you truly think Merge and Oorah are so valueless, and not anykind of asymmetric balance arrangement that compensates for a weapons uograde, which isnthe sole method of scaling on other units, then lets move move Oorah and Merge to to be purchaseable at cost at HQ (or on individual Cons), as paid upgrades, alongside a unit based PPSH upgrade that becomes available at T1-T4.
This way, you can get the mid-late scalingbthat you desire, by buying one or all of them, same as everyone else, separately and at cost, like everyone else.
If you truly think Oorah and Merge have no asymmetric significance at all in terms of the value and utility of Cons (especially as free from start), you shouldnt have a problem with this.

So how about this:
-Merge and Oorah removed as native from Cons.
-PPSH Upgrade at T1-T4. According to your figures, 3xPPSH for 60-75 Muni (weaker than doctrinal).
-Merge Upgrade either from HQ as a universal for MP/Fuel or individually for Muni.
-Oorah Upgrade either from HQ as a universal for MP/Fuel or individually for Muni.
-Molotov/ATNade Upgrade from HQ would possibly need to be made cheaper.
This way Cons would and can scale, at cost, in the same way as everything else, and still retain Oorah and Merge as options
If you truly believe, as you say, that Merge and Oorah have no inherent assymetric balance value as currently free native utility abilities, as compared to the sole weapon upgrade option for scaling on other units, then you shouldnt have a problem with the principle of this, and the costs ofc are just a simple matter of tuning.
