I do not know if it will work. But i do know that there is no difference in how you wired it except how it looks. So you will be getting the same amount of power to the ESC's in either case.

Either way is fine as far as the ESC is concerned. I used Solution 1 since it was one less joint to fail (or solder).

Just be sure that the polarities are maintained.

yep i like solution 1 too
as for the capacitor i'm thinking of using the 1000 uf 25v for both fxr versus 2 cap that came with the fxr
the one cap should have more than enough power to cover both
what do you all think?

I would use the ones that were supplied with each ESC, they are smaller and react faster since the capacity is much less. The 1000uf would work too, but you might see a little bit higher ESC temperatures.

I prefer solution 2 so that the resitance loss through the length of wire is equal to each esc. Since the additional length of wire to the 2nd esc in solution 1 is so short, there's probably negligible loss due to resistance and wouldn't bother me too much though.

^^ the loss would be so insignificant it wouldn't make any difference in the real world, and if you're concerned about that, just ensure that's the rear ESC so if it does somehow be underpowered, it's ok.

Just an observation, but might not want to wire just like the pics shows. You would be running from input to output the way it is shown. I'm sure the picture was just for illustration. But just saying.

correct the photo is not the final solder wire
just for illustration

so solution 1 to me is more simple, as long as i have the rear esc on the end of the wire and leave the front on the middle
everyone agree?

This is how I wired mine and it works great. And about the caps I never used them and I have no temp, glitch or other problems.

where should i place the 1000uf - 25v capacitor - position A or B
My guess is position A

it really wont make much of a difference, if you're only going to do 1, i would put it at B since it would just be easier to solder.
