Change of Name - No Dual Citizenship (Indian Passport)

Hello

I need guidance on Name change approach in the process of obtaining British Passport via Naturalization.

Background
We are family of 3 (2 Adults, 1 Child) and hold ILR for last 2 years and now planning to apply for naturalization (and British Passport).
I entered UK on my Indian passport which is issued on my married name (AB PQR XYZ) and this married name is used on ILR, BRPs, Bank Accounts, Driving License etc.
India does not allow Dual Citizenship, and I will have to surrender my India passport after obtaining British Passport.
Name change process in India is time consuming and I want to avoid it.

A Wish
I want different name (ABC PQR XYZ) on my British Passport (ideally on Naturalization Certificate too).

Guidance Needed
After going through various threads in the forum I think below are possible routes to make this wish come true.

Route 1 –
a) Apply for Naturalization with existing name
b) Apply for Birith Passport with existing name by sending current passport.
c) Change name via Deed Poll
d) Apply for renewal Birith Passport with new name by sending Deed Poll
e) Apply for name change in Bank, HMRC, DL etc

Route 2 –
a) Apply for Naturalization with new name
b) Change name via Deed Poll
c) Apply for Birith Passport with new name by sending current passport+ Deed Poll
d) Apply for name change in Bank, HMRC, DL etc


Route 3 – (want to avoid it)
a) Follow process of change name in India
b) Renew Indian passport with new name (No change to BRP, DL, Bank, HMRC etc)
c) Apply for Naturalization with new name
d) Apply for Birith Passport with new name by sending renewed passport.
e) Apply for name change in Bank, HMRC, DL etc

Questions
1. Which is permissible route and have higher chances of not getting stuck with horrors of name change as per other threads?

2. Is it possible to cancel my Indian passport after obtaining Naturalization certificate? So that I do not have to send my current passport during British Passport application.
