Whilst that is a nice idea At Lakes, the RFT limits the options to the Boeing 737 Max 8 and the Airbus 321 LR/XLR (neither of which operate as a combi or a freighter as yet I believe). The C40 is not built from a 737 Max airframe, instead it used bits of the older generation -700 & -800 737 NG airframes. So I don't think it can be considered as a viable contender, and neither can the A330 or even the C-2. The brochure you linked is from 2016, so likely no longer current.
The first Airbus 321XLR has just entered service with Irish airline Aer Lingus literally a few days ago. Probably a bit early to say how good it is (and whether Airbus' range claim actually stacks up). To get FAA certification, I read they had to make some changes.
The 737 Max series has had it's fair share of problems (grounded worldwide for nearly 2 years after two accidents in 2018-19, followed by a large number of cancelled orders, claims of poor quality workmanship &, recently, industrial action). I wonder exactly what the tender refers to when it mentions "the competitiveness of the market for aircraft of this type".
Then there is the issue of the current backlog of orders that Boeing (4000+) and Airbus (7000+) apparently have for the 737 Max & A320 series, just for commercial operators. Hence I am sceptical of the tender actually being able to be filled even by late 2027. That's why I consider this whole process a waste of time. And that's on top of a passenger airliner simply being the wrong type of aircraft for the job in the first place.
