Fight result between big FBB vs smaller female MMA fighter or wrestler?

[desmo006]

I Wonder how could be the final result in a submission wrestling fight between a
big female bodybuilder or female powerlifter around 5'7 and 170/180lbs against a real female wrestler or good MMA fighter
but lighter, around 130/135 lbs, with the same height?
Do you think the FBB could have a chance to win that kind of fight or she should be quickly dominated because size does not always matter?

Helen von Mott (BJJ) vs Bunny Glamazon (bodybuilding)

Becky levy was a big fat girl at this time overweighted ...and bunny Glamazon is tall and sexy but she is not a bodybuilder at all.
The most of her power is in her breast ...not in her biceps neither in her legs 
Take a FBB like marika Johansson or some muscle girl of her size instead of this kind of women , the result could be very different in a fight with a
wresler or a female MMA fighter.

Don't mean to 'bump' this for nefarious reasons, but i just noticed this and thought that I would throw in my £0.02-worth.  Here's a match-up between local contenders which I think sort of fits the bill in the original post:

Scottish-based firefighter and bodybuilding champion Lorna Biggam v Scottish bantam-weight UFC challenger Joanne Calderwood.

Lorna is 12 stone/77kg and is 5'7"/1.71m tall
Jojo is 8 stone/52kg and is 5'6"/1.68m tall.

Here is Lorna:



Here is Joanne:



I think it could be a very interesting confrontation. What do you guys think?
