What If the announcement for a Tenure-Track position in a research-intensive university does not request a research statement?

If a TT position is announced in a research-intensive university, and they only request to apply 1) a letter of interest and 2) a CV (No research statement is required). Would you still submit a research statement letter or would you just include in the letter of interest more details about your current and future research (this might require making the letter little longer ~3 pages)?
