I made the mistake of buying only 2 Goodyear Asymmetric tires. They are a performance summer tire. Right now I have 4 all season tires in which the front tires need replacing.
It sounds like OP will be mixing worn AS tires with brand new summer performance tires.
Strange mix.
As you know it is not optimal but it may be even worse if your vehicle is AWD.
What car and what are the old tires? How much tread is left?

^^ This.
With AWD or 4WD, matched tires are absolutely needed.
2WD may be different. In the past, when I was young, had no money and didn't know any better, I had done this. But my cars were little econoboxes then, and the tires really weren't too different from what was on there already: aftermarket low-end A/S with OEM low-end A/S, with similar treadwear levels (new vs. used for about 12,000 miles).
The OP's situation is different. Worn A/S matched with super sticky summer tires equals a recipe for disaster, one end of the car will stay planted on the road, while the other end loses control in adverse conditions.
I wouldn't do it.
Putting the better tires on the back is the best approach.
