Frame has to be modified to allow the trans to fit which I believe is $2500 through DF along with ZZP conversion kit. Is it worth it??? That is a decision only you can make as it comes down to is it worth it for you. I would recommend viewing Desert sasquatch's build log for information as he is in the process.

Desert Sasqwatch #155 Track (mods) - 08 SS/TC crate LNF F40
Reintroduction: Tim in Queen Creek (Phoenix) AZ, formerly in Laveen AZ. I have been wanting to build a kit car for years and looked at many that just did not quite fit what I wanted or fit within my budget - Lotus 7, Cobra, Cheetah (all too expensive) or Exocet (too ugly), Nemesis (too difficult...

Is the Saab transmission a 5 speed or a 6 speed? Saab installed both the F35 and F40 into numerous models, both supercharged and turbocharged.

From the 2 cars at the Pull a Part both are 6 speeds.

From my build log. I am one of the few who went F40 before DF offered the option and had to figure it out myself
The F40 is the strongest transmission option we have.Here is the work they did to fit the F40. The main bar was cut out and replaced with one with a 6* bent in it. The upright bar was cut and a new bent section was added. It is sleeved and will be plug welded so it should be strong. They also remade both angled bars that connect to the main bar. I am not exactly sure why, but I told them to do whatever they thought was best to fit the F40.
They also completely remade the trans mount.

Your design solution looks to be very sound and should have enough bracing and stiffness to keep the frame tubes located and in place under load. For the bottom of the plate, if there is not enough room on the inside facing the transmission, but a 'L' stiffener on the outside of the middle frame tube, as @Gtstorey has suggested. And make certain there is at least 1.5 inches of overlap with the middle frame tube and the 'L' stiffener when welding it all together. The bottom 2 speedholes (Yeah!) will have to be moved up a bit.

Not enough room to L the inside.
Trans would hit.

I think I’ll have at least one redesign that’s for certain. I went 1/4” thick on this one and that may be a bit overkill but I thought this is probably not the place to be under built. Elimination or changing bottom speed holes is also a possibility. I made 4 of these in case anyone wanted one lol.

I have a brand new Saab 6 speed shifter, it looks just like the Cobalt 5 speed shifter and installs in much the same fashion with the DF supplied hardware.
The only difference is the baseplate is slightly different and I would include a DF manufactured plate to weld in place of the existing plate on the tunnel cap.
IM me if interested.
