I think Vinny was trying to say that you will fall foul of the rules. See the links that Vinny has posted, and/or see the bits highlighted in red below:
Requirements for indefinite leave to remain as the unmarried or same-sex partner of a person present and settled in the United Kingdom295G. The requirements to be met by a person seeking indefinite leave to remain as the unmarried partner of a person present and settled in the United Kingdom are that:
(i) the applicant was admitted to the United Kingdom or given an extension of stay for a period of 2 years in accordance with paragraphs 295AA to 295F of these Rules and has completed a period of 2 years as the unmarried partner of a person present and settled here; or
(i)(a) was admitted to the United Kingdom in accordance with leave granted under paragraph 295B(c) of these rules; and
(ii) the applicant is still the unmarried or same-sex partner of the person he was admitted or granted an extension of stay to join and the relationship is still subsisting; and
(iii) each of the parties intends to live permanently with the other as his partner; and
I don't think the 6 months on a fiance visa will count towards the 2 years.
If you are working could you get a work permit or qualify for HSMP?

Someone else may have some suggestions.
