I hope you've got it working after our PM's.
I'll tell you what I've done: I've done another partition, marked as bootable, called "Work" in my Cf, with 400mb, but you can make it just with more than 43 or 46mb that is what it uses, and I've copied there the CWBLite with the 1.3 theme.
I thought I would need to change something in the startup-sequence for it to work, but not.
So if I want to boot with this second "OS", I just have to press both buttons of the mice and select the partition to boot, in my case DH4.
The only "problem" is that you'll have botting with whatever partition some icons of the other, but if you can arrange it, it will be fine.
Another thing: I only can use 4mb of my Hawk ramboard, just like you, and using CWBLite I've could run games I coudn't before (like AlienBreed Aga) with CWBAdvSP, just because I've got more free ram I think. Well, surely I could with CWBAdvSP using 4 colors, but it's better to use them with this.
Edit: Thomas has remind me a recent thread:

I think I will try it, to avoid repeated icons.
Edit: I coudn't make the link to work right, but what I'm doing now is selecting before booting the partition I want to be disabled too.
Edit: No, now I boot directly to DH0 without any other icon, and only use the early menu to boot from the second and hide the first:
