Maybe, but not now.

I know, my converter supports alpha channel during rendering.
This is a full 64-bit RGBA PNG, with 16 bit for each channel:
And here are some conversions with different background colours:

By this way, alpha channel is supported: during rendering.
However, on the Amiga, nothing supports alpha channel, nor from hardware, neither from software. Besides, even if i would made a custom IFF chunk, which would contain the alpha data, i cannot expect existing software supporting it.
Simply there is no any point storing the alpha data.
