  If one is "really" inclined to consider Audio mods for the DX-60, I'd 
give serious to the mods published by the late WC3K.

Bill was a satellite engineer, and spent a large part of time in his 
"laboratory"/ham shack, working on the DX-60.  He made a number of 
modification, including adding 160Mtrs, PTT, and audio.

He used his to drive a 30S1 on occasion, along with a 30L1.  sometimes 
it was barefoot.

There really is no need to attempt to make it a plate modulated Tx.  
Controlled carrier as it was designed and built, works very well.  The 
problem is that some operators push the audio too hard.  This is 
particularly an issue sine the audio gain is a pot INSIDE the radio, 
only accessed by opening the cabinet.

Bill, WC3K, had a simple mod for observing the level of modulation, 
without drilling holes.

Most if not all were published in Electric Radio.

I "may" have the very last mods by him, that did NOT get published due 
to his unfortunate departure.
