It should work, but:
a) you will have to add cold boiled water to the portion of heated
wine to replace the water and alcohol that has evaporated.
b) your wine may develop "cooked" flavours, even from mild heating.
c) you will have to be -very- careful not to introduce contamination.

You may be better off making a batch of low-alcohol wine for blending
purposes.
