Another much more random and complicated option (I don't know your specific situation and/or willingness/ability to pursue and/or stomach all the possibilities and accept the various potential liabilities) might have you looking into getting ahold of a used Festool track saw with larger capacity.
Used Tools
In the past, Festool sold the "AP 88" and the "AP 85", though never, to my knowledge, in N.A.
Here's an AP 85E for sale on eBay.de:

An 88E sold on eBay.de back in May:

Often sellers are willing to ship internationally.
Of course, these are likely 50hz machines running on 230V (or thereabouts) so you'd need to run a dedicated 240V line (if you don't have one already) to where ever you plan to process the material and accept the slightly higher motor speed that comes from running a 50Hz machine on 60Hz. Alternatively, you could buy a voltage transformer (I think some will even adjust the Hz output). I think you'd still be way ahead of $2000 for a new Mafell. Parts are still available for these machines too. You could even pick up two and have one for parts.
If these machines are not your cup of tea and/or compatible with current Festool guide rails (I'm not positive they are) then you can disregard my idea. Someone is sure to pipe in with some personal knowledge of these machines. If not, you could create a new post and ask your questions.
Brand New
Or, if you have 240V readily available (and all the other aforementioned considerations met/resolved), you could go grey market (and I'm not advocating you do this) and acquire your very own HK85 and be the envy of all of us North Americans here on the FOG:
