bucklers and dervish dance

[Diminuendo]

If I strap a buckler to my main hand (the hand holding the scimitar) can I still dervish dance?

Yes, but you would not be able to use both in the same round, and you would suffer the -1 penalty to hit for having a buckler on your weapon arm.

I am aware of that, I interested in making a Holy Vindicator of Sarenrae

I don't think it's really a viable option

Why not Slashing Grace/Effortless Lace?
