Somehow, I think this is a good name. I think the miro part is light and the slav part is more heavier, to make an oddish name. It's a bit odd, but I'm now rather fond of it. Snort!
I interpret this name as meaning "glorious in peace" (and similarly for other *slav names, e. G. Svyatoslav="glorious in saintliness", Mstislav="glorious in revenge.") I have no basis for this other than being a native Russian speaker and thus having some intuition for old Slavic word formation.
