An extra tab on the HTC home plug in?

[BustedNuts1]

I think I already know the answer to this, but was wondering if anyone had any creative suggestions.
Is there a way to modify or add a tab to the HTC home plug in? Specifically I wanted another launcher. I don't need the weather tab (since I use WeatherPanel, thanks Storyr), could this possibly be changed? I know that some people use spb pocket plus along with the HTC home plug in, which would work if I wasn't so opposed to spending $30 on software, most of which I already have (X-button, touchnav, etc). I emailed spbwarehouse and asked them if could buy just the today plug in, but they said it wasnt possible. I've also looked into the iLauncher, but I don't like it as much.
So, in sum, is there a way to change the weather tab on the HTC home plug in to another launcher, or is there a way to add another one.
