Hi Ben,
I am not 100% sure what exactly you wnat to achieve.
But why don't you use 2 jpg's with one as a masc where transperency is
black.
You can generate an alpha channel form this.

I'm working on a game with some large images (up to 4k x 4k)
The pngs with alpha channels come out at 5-10MB each and we need to put a
few large ones and many smaller ones in the game.
jpeg-xr would do the job, but we are targetting Flash 10
This blog shows how to combine a jpeg with a png alpha mask to get file
sizes down, but it is for HTML5, although they were able to use a flash
converter successfully:

Is a PNG transparency mask the best way to go, or are there other options
to get the file size down?
I've found one set of code here:

I thought I should check here before using it, as we're going to need to do
a lot of these...
Thanks,
Ben
