Looking for Minerva Titanmaster toy

According to his toy review, Siege Jetfire comes with a cockpit that can seat a Titanmaster or Primemaster figure.

Because he shares a color scheme with Minerva Titanmaster, I thought it would be fun to acquire her to be his pilot/passenger:

This figure is only available with the Optimus Prime bomber set, but I am wondering if the single unit is available for purchase second-hand or used.
Does anyone have any information on if I can purchase her separately this way?

Might be easier to just by LG God Ginrai then keep Minerva and sell off the rest. <shrugs>
Maybe find a loose complete LGEX God Ginrai to pay under RRP.

@GoktimusPrime
I might keep Cab as well, if he's not part of the main toy.

I did sell a Combiner Wars Devastator to TransformerLand, but the shipping costs were so prohibitive I wouldn't be able to do that again.
So I'm uncertain where I could sell the part I do not want more locally.

According to BigBadToyStore, God Ginrai is like 140 USD (200 AUD).
That's a bit much to pay just to get two 10 AUD figures in my opinion.

But hey, if anyone has the toy set and wants to sell me Minerva and Cab at a reasonable price, I'm okay with that.
