It's not too small. Done it with Crestron 6L's as well. You're an RTI dealer so you probably have a K4 sitting around, head on down to the apple store and shell out the 250 and try it yourself if you don't trust me.

Regarding the conversion we take component out of ATV into a 1x2 component DA, one output goes into composite downconverter the other into the component video distribution. Done. Works perfect.
