Is a HAM background possible for OS3.1?

[Paulie85]

I currently use a 16 colour WB which is nice and fast, but I am not a fan of the dithered wallpapers. Having used AMOS back in the 90's, I seem to recall being able to overlay one screen on top of another(dual playfield?). So, I was wondering if there is a tool which would,for example, allow me to make my WB background transparent and then overlay it on a HAM screen.

Is this at all feasible?

Thanks for the help.
I've just tried the HAMWB package but haven't been able get it working properly.
I don't see any example pictures included but any HAM images I've tried to use as backdrops look like 16 colour images. The docs state that it allows you to use a web browser in 4096 colours so I tried AWeb but it just looks like it's using 16.
Apparently a Rexx script is included to allow icons to be converted to HAM so I will try that later.
