The RAF.1 (an air cooled V-8 based on a Renault design) first ran in 1913, so you may have missed the boat on that one. Though it did get an experimental supercharged version (RAF.1a) in 1915. By this point the RAF.2 air cooled radial has already been running for almost a year. The RAF.3 V.12 liquid cooled development of the RAF.1 has just had its first test run, or is about to. It will then be developed into the RAF.4 and RAF.5 (a pusher version of the RAF.4) in December. The RAF.3 would later get a high compression version in the RAF.7 and the RAF.8 would be developed in 1916-1917 based on experience with the RAF.2.Initially an improved RAF.1 but who knows where it will go.
So at this point Heron’s work would likely be used to improve the RAF.4 and .5. Possibly in refining the RAF.3 if the findings can be verified quickly enough.
