I had my FLR(M) approved yesterday at Croydon PEO.

When we asked the case worker about BRP and passport name changes, he seemed to suggest that it would be easiest to change my name on my passport
just before applying for ILR (rather than do it now and wait an undisclosed amount of time- he said he couldn't comment on the wait time for BRP replacement cards

).
He didn't mention it, but I read if I didn't notify the UKBA of my name change on my passport within 3 months of doing so (to get a replacement BRP so it matches my passport), I can be fined £1,000 and have my stay shortened.

I don't want than to happen.
If you change any personal details listed above or any details shown on your biometric residence permit, you must apply for a new permit within 3 months using application form BRP(RC). If you do not do this, you may have to pay a financial penalty of up to £1,000 or we may shorten your permission to stay.

within 3 months of applying for ILR, I wouldn't need to get a replacement BRP (currently taking 3-6 months!), right? My ILR BRP be issued in my married name (as my passport would be), right?
My FLR(M) will expire 10 December 2014 and I understand I can apply for ILR up to 28 days before that. So from 12 November- 10 December 2014 I can apply by post or in person.
If I renewed my passport within 3 months of my appointment or of sending in my application by post, would there be any issue? It seems better than waiting 6 months for the BRP and not being able to travel.....
It seems like passport name change renewals sent from the UK take about 3 weeks..... anyone have experience with that?
As long as there were no delays with the passport and it were within 3 months of applying for ILR, could this plan work? Or is it pushing my luck?
