will this work?

[dan-htc-touch]

hey all, I will be recieving my p4000 in a week, and I want to know if what I am thinking of doing will actually work, and greatly simplify the upgrade process for my. With my vogue I do all flashing from sd, and I want to do the same with the titan, so here is what I am hoping will work:

1. use dutty's nbh tool to extract radio from sprint update
-I assume it is the 785.nb, can anyone confirm this?

2. use winzip to extract hard-spl-mfg, and inside is olipro-2.40-hard.nb

3. create custom rom using ppckitchens 3.35 selections

4. use dutty's nbh tool to extract .nb's from custom rom

5. use dutty's nbh tool again to package up
-785.nb as radio
-olipro-2.40-hard.nb as spl
-use mainsplash, secondarysplash, and windows.nb from custom rom

Once packaged, will I be able to flash this all in one shot, or does the device have to be unlocked seperately, and then flashed with an nbh without spl?
