Maggies with Tubes?

Hey Guys,
For the last few years I have been enjoying a pair of 1975 KHorns as my main speakers but just sold them a couple of days ago.
Still have a pair of 1979 Cornwalls that I am currently driving with a Audio Space Galaxy 300 (300B in push pull, 21 wpc).
I stopped into a local shop and listened to a pair of 1.7s driven by a, I think Mac 252... and they sounded fantastic!

If I was to add a pair of 1.6s or even better a pair of 1.7s, would my Galaxy be able to drive the Maggies?

Keep in mind, I would not be expecting the output that I am use to with either of my Klipsch speakers, but I am hopeful that the Galaxy could drive both the Corns and Maggies.

Or, should I be looking at another amp (perhaps a KT88) that would be better suited to drive either of the 2 speaker systems?

Thanks in advance.
