Original rom (rooted) + Custom rom Dualboot possible?

Due to storage constraints that would not be feasible.

As you know the OS resides in the ROM drive which is already filled.

The whole point of the ROM drive is the security it brings.

If you get rid of the Read restriction you are open to all sorts of vulnerabilities.

Although since it's not be done before doing it solo on your machine would mean some sort of security just because noone else knows.

But you are looking for a solution outside meaning you don't know how to do it and hence you have to look for a provided solution which means it will become popular therefore you will be susceptible to malware practices.

Yes amos I know what you mean, but I was talking about it in context with today's need for security on these devices.

I meant why a ROM drive was implemented over a RAM drive on a Android Phone.

It makes good sense at a security stand point and it also provides a way to "Reset" the phone.

In todays world security is more important on something like a smartphone then it ever was.

My bad on saying:

forgive me for saying that, but ROM drives serve a different purpose than the used to.
