No but the Alltel WM5 ROM kicks ass and is what I'm currently running on my Mogul.
If you're not well-versed in toying with flashing and running programs to fix other problems, etc., then you would do best to wait for the devs to finalize the tools.
I installed Hard-SPL, which locked my phone in bootloader, had to use a patched exit-bootloader for the Titan to get out of it, downloaded the rom update utility (RUU) for the Mogul, downloaded the barebones Alltel WM5 ROM, flashed it, it errored at the end, then it finished anyway but left me in bootloader, which I had to get out of with the bootloader utility, and then I had to hard reset one final time to remove the very last remnants of the WM6 stuff, then soft reset as soon as the installing customizations screen came up.
Just to give you an idea what you're in for.
