Just when you think you're out, they pull you back in!

I must be a glutton for punishment.  After painting 33 over the holidays, I picked these two up from eBay.  I'm considering getting the saws and knives out to convert these to plasma gunners..a weapon missing from a majority of Praetorian/ Mordian armies.

 

Plus these ones need to be stripped and painted...or are they the experimental conversion fodder?
