Yes. I definitely can recommend this. The same is valid for the timing 
caps of the envelopes (C23 and C25 resp on KLM355).

Regarding the timing of the envelopes: to my taste the range in which 
the short attack, decay, and release rates are controlled by the 
corresponging pots is very narrow, and theres a too wide range for the 
long rates (e.g if I compare it to my moog prodigy). Did you ever think 
about changing the potentiometers? Or adding parallel resistors to 
change the characteristics of the potentiometers?

Theres a "must read" on this topic:
