To be honet, I was thinking about them as support squad (maybe 2 squads)
To all Axis lovers:
No, it's not nerf Jaeger thread. It's thread about Jaeger utility.
You allmost got me on this one.
On a more serious note, I used to love JLIs quite much and the doctrine they are in. Your idea to use them as mainline infantry is not that bad as it could seem - I did that in the past - but keep in mind that they are quite fragile especially nowadays when whipes are happening all over the place, and they are not that cheap to build nor reinforce. They can performe 2 rols for you:
1. support - behind your volks, from where they will snipe models from enemy squads that are low on health;
2. spotter and recon unit. I found them verry usefull in this role with a Puma in the background or a Panther. Or for your teammate if he has a Jagdtiger in the back or a PACK 43. As spotter and recon you can place them mixed with your volks blob or somewhere in front waiting in camo stance behind something. They will provide you a good view on the battlefield. They can scavange also like pios and volks do and can boby trap teritorry as obers can do.
Have fun with them.
