Vintage? I´m vintage!
IMF´s are professionally designed speakers, and excellent ones at that. These speakers adopted two different sets of drivers in the MK-I´s and the MK-II´s, but all of them were first rate drivers.
You had better be quite sure you know what you´re doing before you start messing with a better than average speaker.
What is it you find lacking in yours? If it´s the mids and highs you find lacking, the fault lies probably with faulty drivers or crossover components. I´d recommend you check them out and have them fixed up before you think of replacing with different ones.

These use the B110 mid-range units, reputed to be some of the finest the ever made. They are used in the Rogers LS3/5A's and lots of other great speakers. Linn Isobarik's use two in each speaker. They are brilliant drivers, so it may pay to re-cap the crossovers and see what you think.
If you don't like the 110's please send them to me! One of my t-lines has a dodgy one I've been meaning to replace for a year now.

Aside from maybe refreshing the crossover caps, I don't think it could be very much improved without compromising the performance or changing the excellent sonic character. Further, any modern driver is likely to be much more efficient than the originals, throwing off the balance.
The only, and really I mean only improvement I could imagine would be to replace the super tweeter with some sore of radial ribbon, and only then if you felt the need to extend the frequency response beyond 30kHz.
John Wright and company really knew what they were doing.

Making up for lost time
Check out this link from the T-line speakers web site; it includes some suggested mods ranging from pretty basic stuff that will not change the physical character of the speakers to more involved ones that are more along the lines of what you are thinking of.

I have had similar thoughts since acquiring a pair of TLS80s about a month or so ago. It would be fun to convert them to the Special Application Control Monitor version:

This could be done, again, without irreversibly modifying the original TLS80.
After much thought circling I have decided to re-cap the crossovers and then see how I feel about it. The more I listen to them (even with 30 plus year old caps) the more I like them
