Seems like one can do much better with transfers here:

 

1D - 1H - 1N:

 

2C: Transfer to Diamonds

      P: TP

      2H: Invite

      2S: GF, D+H reversed

      2N: Invite

      3C: GF, D+H, LL

      3D: High short

2D: Transfer to Hearts

      P: TP

      2S+: GF with SS hearts

2H: GF reversed Spades

2S: GF revesed, Clubs

2N: GF LL, Clubs

3C: Long clubs, 4H, TP

3D: Long diamonds, 4H, invite

You saved room, but you left out GI 4H/5 other. I think you need those. Also, pretty much all of my bids are transfers. I transfer to clubs but your 3C is to play. Shouldn't that be invite?

 

I do like that you left out the impossible 5S/4+H holdings. I just didn't want to remember those. Mine is basically standard symmetric.
