Adding a 250.2 non DR to a 300 DR biamping MA 200 PL

Good morning.  Firstly...

Great running system:

HDX (2 Tb); nDAC; 555PS; 252; SC DR; 300 DR into Monitor Audio Platinum 200s; all Powerlined.

Now, the PL200s require 100 W and the 300 DR only pumps out 90 W. The sound is great, but these are speakers suited for biwiring.  (Some tracks appear to show this.) Yes I've read opinion on passive biwiring, but these speakers are designed for it.

Would adding a 250.2 non DR and biamping passively with the 300 DR work?

(The 500 and the 552 are NOT options by the way, but the 250.2 non DR is - put on the treble maybe.)

I'm curious as to forum opinion, because these speakers are staying -perfect for my room - but I feel the 300 DR needs more juice.

(Yes, music is regularly growing, can't see why the HDX isn't praised even more!)
