Maybe it's just me, but a little clarification would help. Your first statement / question in your post asked what we think of using a 14" rack tom as a floor tom to accommodate your ride cymbal location. That's a good idea. Lots of drummers do things like that to fit that ride cymbal just where they want it.
But then you say that you're thinking of putting both toms to the left of your bass drum.
Do you only have two toms, are you talking about 2 mounted toms to the left plus the 14 on the floor? I'm not exactly sure what you're asking.
