Dapianokid, your idea is 100% correct and is (imo) the best way to do it. The best way for this to happen is to install a custom boot1, as it gets launched first and does not have to be verified. However, all Nspires except for prototypes and Clickpad hw revs A and B have their boot1 flash set through hardware only to read, and not write. And since said flash is housed inside the ASIC on all models except the aforementioned, we currently have no way to get to it to hack it. The first step to do that would probably be to decap and analyze the chip, but that takes expensive equipment, and lots of money. IIRC, there's a fundraiser going on to do the same thing to the 3DS's ASIC. However, it's so expensive that it has to be funded entirely through donations and has not received nearly enough funds to do so, and it's been running for months. So yes, once we figure out a way to make ALL boot1 flash chips rewritable, your plan is the way to go. However, we currently have no way to do this. OR we could beg TI to let us do what we like, but sadly, that's not likely. I sent them an email requesting a dev version of the OS to be put out for us enthusiasts, but I got the standard 'your suggestion has been forwarded to our Nspire team' stuff.
And while we're at it, I can host files as well. I would happily host a full Nspire archive of all files (boot1, boot2, diags, OS, anything really). PM me if you'd like to discuss.
