Maybe not neverending (I've done it in the past, it was hilarious), but seeing as Conscripts are now 3pts/model, it is only 150pts (175 with Priest/Commissar) for the whole unit, so you can have 2 units per Knight. I think a Knight will struggle to get through 100 Fearless bodies in 5 turns.
Company Command Squad =60pts
Priest x5 =150pts
x5 Meltabombs
Commissar x1 =30pts
x1 Meltabombs
Infantry Platoon =440pts

Has a total of 150 Conscripts, 140 Guardsmen, 6 ICs and 20 men in Command Squads. If you get everything into cover, that will take some removing!
I added the smattering of melta because there were points spare and it allows them to harm everything... eventually.
It could essentially place a blob squad onto every objective on the board, and everything has Objective Secured.
