I know it's potentially a Bad Idea (tm), but hear me out.
I've got an HTC Desire, and its internal storage space is severely limited (150 MB, barely), running Cyanogenmod 7.1. I'm not entirely happy with the supplied keyboard, and have tried Swiftkey X Keyboard, to a great satisfaction. Now, since keyboard apps cannot be installed on the SD card when they are used, this eats up more than 15 MB of that precious internal space and severely limits the number of apps I can install.
It occurred to me that I could convert Swiftkey to a system app and integrate it in the ROM, and after that freeze and remove Android Keyboard -- using Titanium Backup. Naturally, I'm not too keen to try it without asking around first, for it can have disastrous consequences.
So, my question really is:
Can I remove Android keyboard if I have an alternative input method application?
