If you have Replicator out (and you really should have), DO NOT draw cards unless you have nothing to replicate in your deck. You DO NOT want to waste clicks drawing cards that you could get simply by playing them from your hand (i.e. Lockpick, MemStrips, Silencer and to a lesser extend R&D Interface).
DO NOT forget to replicate Replicator, you big dump ass. :=)
Mimic is just a back-up breaker against Jitenki/stacking of sentries, you don't usually need it at all, so go for Switchblade.
Switchblade seems like a nice complement to Sage, for sure.
It looks like this would take a lot to set up though ... have you considered trying this in Hayley to speed up all the hardware and resource installs?
