I have consulted my ATPL books (yes I am that bored!) and the Vmca is not affected by weight.
It is however affected by:
1. Angle of bank
2. CG Position (which is function of the position of weight, not the amount)
3. Aileron Effectiveness
4. Flap Position
5. Undercarriage
6. Thrust produced (therefore environmental conditions - in Jet Engines anyway, I can't remember about Props)
7. Relationship between Vs and Vmca.
I would type the whole paragraphs, but I really cannot be bothered!
Apologies for the incorrect debate.
