Can you wire a Tri LED to a MR Vader Saber??

[Thousandlegends]

Hello all....
I have an old Master Replicas ANH Vader FX Saber that broke, is it possible to wire a luxeon or Cree tri led to that saber's board? Would it have enough power to run three LEDs?

I am thinking of putting a red/red orange/white or a royal blue/red/white tri LED or something like that... I want either a red-orange color or maybe a purple, don't something interesting like that.

I would also be using a lithium 3.7v batter pack with that which I already have.

Anyways let me know what guys think... If this would even be possible or not to do

Found an answer....
I believe I can as long as it's in parallel. What I'm not sure about is whether or not the Vader can take the 3.7v input source or not... Truthfully I don't know much about these boards?
