Is it alright to bi-amp with 2 different B&K amps?

I currently own some Paradigm Studio 60v.2 speakers and a B&K ST-140 (105wpc) amp and still want something to drive the speakers better. I was considering the B&K 202+ which is 200wpc for the woofers and then the ST-140 for the tweeters. How do you think this will work? or should I try to get an identical amp for bi-amping?
