Hex Editing Roster?

[MkElite]

Has anyone successfully modified a roster or is even close to doing so?

Like making a player height above maximum, for example 10FT tall. Would be interesting if we could somehow edit it.

Made this in 2k14 30FT tall lebron, I wanna do the same kinda stuff for 2k15 just for the funs.
