I agree. Poorly designed engine compartment will cause problems whether engines are coupled, tandem or single (i.e. early Fw-190A).coupled engines (DB-606) were troubled because the exhausts were at the lower part of engine nacelle

Starting with the He 177 A-3/R2, a modified engine nacelle with a new "power system", the Daimler-Benz DB 610, each of which consisted of a pair of Daimler-Benz DB 605s set up to work as one as the DB 606 had been, was used to eliminate the tendency for engine fires.[23] With the introduction of the DB 610 came several improvements including the relocation of the engine oil tank, the lengthening of the engine mountings by 20 cm (8 in), the complete redesign of the exhaust system which also facilitated the installation of exhaust dampers for night missions, and the setting of a power limitation on the engines which resulted in greater reliability. These modifications, supposedly numbering 56 of both major and minor varieties, were successful as far as eliminating engine fires were concerned,
A problem with the "tandem" arrangement like this is that you get one very looooong engine. Where is the fire wall? where is the back of the engine in relation to the main spar? Is this "V-24" all ahead of the spar, below the spar, the spar runs between the two halfs of the engine with a longer prop shaft from the rear engine? rear engine sits between spars? Spar 'banjoes" around the engine?
Some planes with tandem engines had one engine ahead of the front spar, a loooong nacelle and the 2nd engine behind the rear spar with a pusher prop.

I would envision one engine in front of the main spar, and one behind.
Push/Pull may be mor pratical/easier to develop than the coaxial counter rotating propeller system as well.
