Yes, We considered the same conversion to remove and replace the propane oven with a C/microwave. The new parts cost was prohibitive ($$$)and no one responded with a trade / exchange offer. So, we have a WM microwave ($60) strapped to a cutting board wihich is velcro attached to the counter between the stove and double sink.
The FC20 has one of the (if not the largest) larger counter space galleys in the AS line up. So we have the best of both worlds with the ease - and lower cost to replace -microwave oven should the need arise ... oh, yes, I almost forgot ... the convection oven part. Wife loves the stainless Cuisinart convection / toaster oven ($75) that matches perfectly and sits on top of the stove/oven combo. She shares bread, muffins, chocolate chip cookies, etc. every time out. When off shore power (usually), we quickly and easily power up with just one of our EU 2000s ... one higher load electric appliance at a time, however.
