Sounds like what Msalm came up with is the 7.62x39 Ackley Improved.
afaik the howa is a 0.310 pipe. a 308 pipe is not a big deal because those bullets squeeze down easily. but, i would think a 7.62x39 SAAMI spec throat with a 0.308" tube shooting 0.308" bullets would leave a lot of slop in the throat for 0.308 bullet alignment. may not shoot quite as tight. but probably good enough to plink. and it does allow 0.310-0.311 bulleted ammo to chamber.
as far as a wildcat up to 35 caliber, i think the Russians did that quite early on in their suppressed spec ops (Spetsnaz) rifles. 9mmx39. essentially the same purpose as the 300 Whisper applications on the US spec ops teams. if i recall the 9x39 was shooting 280gr. bullets suppressed.
good luck Grayfox.
