mixing and matching drivers poses the dilemma of setting suitable xover filters. in particular, the morel supremo will not perform particularly well off the dyn passive xover; the dyn MD100 tweet is a 4ohm driver whilst the supremo is 6ohm. impedence helps determine the xover frequency point on passive xovers, so a change here will alter the HP point. likely no good.
as such, when mixing and matching, you need to consider an 'active' setup, relying on active xovers of either a separate outboard xover or those inbuilt into the amp if suitable (i don't think that amp has suitable xovers inbuilt). an outboard xover obviously adds expense, as well as more power wiring and RCA cables, plus fitment. tuning it is another matter altogether.
and of course an 'active' 2-way setup relies on 4 channels of power. with only 25WRMS on tap for the woofers and around 16WRMS (into 6ohm) for the tweets, that will be quite limiting. it will still go to moderate levels and suit daily use, but won't go really loud. you would have to tune the gains very carefully so-as not to push the amp into clipping in a quest for more volume.
so whilst i expect the supremo to be supeior, it will take a fair amount of expense and effort to set it up properly.
