If I were you I'd use what I got. I use to fuss over which mic for this and that until a ran across some useful info. about the subject. Your preamp is more important than the mic in most cases. Mic placement is second to the preamp. The last thing is the mic itself. You already have good mics, all of them! Use your ears to see where to place them and the recording will be great!
 

Best recording of a grand piano I ever made was a pair of TLM-193s in a very nice sounding room.
 
Best recording of a grand piano I ever worked with was made with the Earthworks PianoMic.
 
Both of these were for an exposed piano in a jazz setting, so that's a pretty specific sound. I liked the Earthworks recording better, and I've tried to get a similar result using other Earthworks microphones, but there is some trickery going on with that PianoMic.
 
I happen to like a stereo recording of a piano, but if you can live with something other than stereo consider using just the TLM-193. My tastes only, but I think the TLM-103 would be awfully brash... unless that's what you are shooting for...

As per Bill's post the TLM 193 is very capable.  I would be very keen to ensure stereo recording.  The piano just sounds better to me in that mode.
 
You could either purchase another TLM 193 or a nice figure 8 microphone from another maker like Rode.  With the figure 8 you could do stereo recordings in M/S with the TLM 193 and also use the figure 8 mic in other studio situations.  The deep null on the side of a figure 8 can very useful in a studio recording situation.
Just some ideas.
 
 

not exactly budget friendly, but the TLM-67 is a wonderful match for the TLM-193 if you want to do Mid-Side recording, not sure how the pair would work in any X/Y configuration. However, I have used mis-matched microphone pairs for conventional stereo recording when I wanted an exaggerated stereo image. So who know?

Nice ideas.  Now that I have a pair of Audix scx25a, what do you think of them either in xy or spaced pair the the TLM 193 as kind of a center overhead?  I really need to read up on mid side recording having never tried it. Or is my suggestion kind of the same thing?
