Since more gm is needed, and mu of 20 is sufficient there are a few other choices... The 'get a bigger hammer' train of thought comes to mind. Try an HY40....:) Or perhaps an EL84. Rigged as triode, gain is there, and rigged as pentode, the plate load can be quite low, delivering very good drive to the power tube grid.
