Unless the fest insists on 4K and the rental income would justify the investment, I'm having trouble making a case for this.
To my eyes, a screen has to be at least 50-60 feet wide in 'scope, and I have to be sitting within about 20 feet of it, to be able to see a detail gain from 4K. Also, you take a contrast hit with 4K using a xenon-lit projector, and most mainstream studio DCPs are still 2K only. The latter may change over the course of ten years, though.
I do service one site that has a Barco DP4K-23B, with roughly the same throw and screen size as yours. Sitting in the best seats (for sightlines) in the house, I really can't see any picture quality gain in 4K.
If there is an argument in favor, it's that 4K may be a selling point for private rental customers. Some indie and screening room customers who don't have 4K are starting to tell me that this is costing them business.

With 60 shows a year, it is probably hard to make the case for a 4K DLP machine.
For me, the case of 4K is not so much dependent on screen size, but much more on theater seating configuration.
There is an increasing trend to maximize the screen size compared to the size of the room and to put people as close as possible to the screen. This increased form of "immersion" is often sold as a premium concept (PLF) and does, in my opinion, only fit a limited amount of content.
In those kind of configurations, even 2K content on a 4K projector will have benefits for those sitting close to the screen.
For traditional setups, the benefit of 4K is much more limited. It will primarily benefit those sitting in the first few rows of the screen. The reduced contrast of the 4K DLP machines further negates their purpose, in such a setup.
