Yes of course Andrew,
As a matter of fact the chap that supplied most of those Renesis engines is 
local to me, but I didn't buy one as I was looking at needing Peripheral 
ported single rotor engine. However I noticed the Renesis engines without 
the fancy inlet manifold was similar in power to the RX7 - therefore no real 
advantage. I did however buy a Renesis rotor and cut 3mm apex seals grooves 
for the higher compression and found out later the higher compression gave 
only higher torque, but no real advantage in hp. No real advantage in that 
either but they were half the cost.
The larger eccentric ( how large ?) will improve torque and the bigger 
volume will improve HP- so that's good. The rest is just suck and see.
