With that kind of drive requirement, you could skip the 100 watt amp
on the K2 or K3 and go directly to about 700 watts out using the QRP

If interested there's a guy named Yuri near Seattle who has a board
with 12 MRF-
150s on it that he tested I think with 25W drive for 1.1KW output.
I don't recall
what the power supply was. Think he wanted something like $350 for
it. Add may
still be on QRZ.com.

based theirs on that design)
