I built my KPA100 15 years ago or so and only recently I investigated 
updates. The KPA module has seen a number of design updates over the 
years and it makes sense to investigate. I've updated mine (thanks 
QRP-shop for getting the mod kits in Europe, through Corona times!) and 
at the end of a long evening I have a bag of swapped-out parts and a PA 
that worked quite a bit better, feels like a new unit.

I have not used one of the upgraders (being in Europe, postage and 
customs would probably have me mortgage the house, frankly) but I do 
recommend updating. It is too bad you don't have the setup to do it 
yourself because on K2, these mods really are simple and can be done on 
the kitchen table.
