Interesting bike choice. That is either a "29er", or a 700c Cross bike. So, a little different conversion.
26" to 700c is quite a bit tighter with vertical space around the tires.
Going with a MTB does force a moderately wider Q-Factor on the crankset. I think I do prefer a slightly more narrow Q-Factor from road bikes, although that may depend on a person's body build. But, going with the MTB base does give a fairly long front triangle and low bar position which would be good for TT.
I almost picked a more modern 853 MTB frame off of E-Bay, but it was a little bit longer than I needed.
When changing rim sizes, if one wanted a versatile bike for quick conversions back and forth, then disc brakes would be nice.
