Good Luck.

It is better to do B.Tech lateral. AMIE is good for people those are in jobs. But, not good for fresh Diploma engineer from job point of view, because most of the recruiters ask about the regular B.Tech degree.

Yes, you can do it, but it is better if you have a Diploma in Architecture done before B.Tech in Architecture, as it will benefit you.
Thanks.
