Cayin TA 30 with KT 120 tubes?

I have a Bizzy Bee modded Cayin TA 30 currently loaded with KT 88s. According to Paul @ Bizzy Bee (RIP), the amp can take KT 90s which I have used on this amp, as well. Just wondering if it would be possible to use the new KT 120s. I've been seeing quite a bit of favorable reviews on the KT 120s and I'd really like to give it a shot. I'm just trying to wring out as much power for my not so super sensitive speakers.
Thanks in advance.
