The only differenence betweeen the compat exec* syscalls and their native versions is the compat_ptr sign extension, and the fact that the pointer arithmetics for the two dimensional arrays needs to use the compat pointer size. Instead of the compat wrappers and the struct user_arg_ptr machinery just use in_compat_syscall() to do the right thing for the compat case deep inside get_user_arg_ptr().
