Quad-booting a superkick A3000

[Failure]

I have an A3000 with the old superkickstart ROMs in it.  I recently put the machine back to factory using the original disks, so now it has a 1.3 kickstart and a 2.0 kickstart.  I also have a 3.1 superkick disk, which I used in the past to put AmigaOS 3.9 on the machine.

Basically, I want to be able to run four OS on the machine.  1.3.2, 2.04, 3.1, and 3.9.  I have three things I was curious about.

1) Is it possible to have all three kickstarts on the HD?  I assume not, I was planning on using 3.1 kickstart from floppy for occasions where I needed it.

2) Is there a method for multi-OS booting besides the early boot menu?  The early boot menu isn't horrible though.

3) And the question I am really curious about.  Is there a way I can remove the kickstart from the machine's memory without powering the machine down all the way?  A cursory search of Aminet didn't turn up anything.  Something like a "reset-all-the-way" utility or method?

Any tips to help me get this thing switching OSs with a minimum of fuss is appreciated!

*edit* it might be fun to put AMIX on it too and have it booting 5 OSs, but I don't have the HD space for it

Ok, well here is where I am at with that thing.

I got 4 OSs installed like I wanted.  1.3.2 and 2.04 boot if their kickstarts are loaded with no further intervention; 3.1 and 3.9 must be booted from the early boot menu after the 40.55 superkick is loaded.

I do not really want to buy another kickflash ;-) so I came up with a kludge.  After installing 2.04 I made a copy of the kickstart to kickstart2.04.  Then I ran upgrade_2.x and installed the 3.1 kickstart, and made a copy called kickstart3.1.  I will write a script that renames the copied kickstart that I want to run to just devs:kickstart and reboots the machine.

The reboot is the problem actually.  Neither program suggested seems to clear the ROM image from memory.  I wonder if this part is going to be possible or not?  This is a bummer cuz I don't like spinning that ancient HD up and down.
