General Custom font replacement (Bytafont or otherwise)

Hi, everyone. I have been a long time user of both the iPhone and the iPad. I am pretty familiar with Cydia, adding additional repos, and general Jailbraking iOS devices. My first iPhone was the iPhone 3, and my first iPad was the iPad first generation.

I am currently using iTunes 11 on Windows 7 X64. I currently am using a AT&T iPhone 5 64GB, and a fourth generation wi-fi 64GB iPad. Both are running iOS 6.1.2.

Both are already Jailbroken via Evasi0n. I also already legally own iFile, Auxo (even though like many am still patiently waiting on the iPad version of Auxo release), Zephyr, Nitrous, ResetAllKiller, SoftwareUpdateKiller, OpenSSH, and have used Bytafont before.

However, despite the pros or cons of the decision to have Bytafont be copyright friendly or not, I do legally own copies of the fonts I am wanting to use with my iPhone and ipad. Unfortunately, even after emailing my query directly to the Dev of Bytafont, I was shot down.

I am able to make use of WinSCP and iFile. But, the fonts I would like to use do not currently exist on Bytafont or anywhere else I have been able to find on Cydia.

Is there any option to make the .ttf font's I am wanting to use, and convert them for use with Bytafont? If so, what software would be most suggested, and what basics steps would I need to follow in order to convert them, and put them on both my iPhone and my iPad for use with Bytafont? Would it be easier or more suggested to just copy the default iOS fonts and convert the fonts I have and SSH/iFile them as replacements? Any specific file permissions I would need to set for doing either with Bytafont or just direct font replacements?

Thanks for any suggestions and advice anyone is willing to offer.
