PocketBreeze and PocketWeather OEMs

[ChronoT52]

I'm attempting to cook my first ROM, and have followed the steps to try and create some of my own OEMs. Namely, I would like to try to make one for SBSH's PocketBreeze and PocketWeather, the latest versions. Additionally, I was hoping to make one for the latest version of iLauncher.

Noting fully that nobody seems to have attempted this, are there problems or difficulties in making OEMs of this particular software? Additionally, can I download the existing iLauncher 3.0.0.4 OEM and simply patch in the 3.0.0.5 files?

As this will be my first cooked ROM, I'm a little timid to go ahead and create the ROM without some input from you all. Thanks in advance for any assistance you can provide.
