T105 6V batteries ARE generally rated around 225@hours at the 20 hour rate, thus two of them will rate 225@hours @ 12V. This will be a reduction in your amphours, but if the construction is better than the 12V your were using, it may be worth the tradeoff.
I am not aware of any standard 12V battery size that rates 130amps at 20 hrs.. The group 31's typically rate 100-110 and the 4D's are generally over 150-160. What exactly do you have there?
In any event...there is NO problem mixing 12V batteries with 6V batteries paired as 12V's as long as the construction type is the SAME...i.e. flooded or AGM or GEL.
I think Dawgs concern is misplaced...as even if you lose the 2 6V batteries...you will still have a working 12V battery. If the pair of 6V's were your only source then I would agree.
