Yes -- see my post #14 above. You can resistor mod the stock driver to get more amps. I added an R100 and got a nice boost - should be almost double the amps. Refer to the driver pics in this thread OP: https://budgetlightforum.com/t/-/28129 for detail view of the stock resistors (R180 and R150 in parallel).
You really should have gotten or waited for the 26 mm copper MT-G2 star - much much better to fit in a Y3.
