Two Questions:

1. On the SIP phone, will this special conference function be needed
on both incoming and outgoing calls, or just one of those?

2. Does the analog phone have to do anything else?  Should it work
like a normal phone when it's not doing this special conference
function?

You should be able to do this, like you said, by dumping both phones
into a meetme conference.  There would be two tricky things here A)
getting the analog phone to automatically go to a meetme conference
whenever it is off-hook, B) getting outgoing calls from the sip phone
into a meetme conference (incoming calls would be easy).

I think A) is probably not possible, given that you are using an
external ATA device.  That device would somehow have to send the
off-hook status back to asterisk via sip messages (I think there's
actually a bounty for this).  This should be possible if you were
using an internal zaptel card rather than an external gateway.  If the
answer to question 2) above is yes, you would have other problems,
too.

A good compromise to the problems of both 2) and A) would be to put
the analog phone into a special context where you'd have a one digit
press for each function (e.g. press 1 for normal phone, press 2 for
conference).

Still, unless these users are really ornery, I'd probably just make
them learn to transfer and dial into a conference.

In fact no, I should have explained better, but in the old system one
phone was analogue and the other was a multi-line digital Nortel
Meridian phone. The one phone has to be analogue because it interfaces
with a radio broadcast phone patch.
