That is kinda what Bee is, but yea they should have waited a couple years. Course the problem here was that Bee was already starting to film before TLK even released I believe.
Bee would have been a great reboot point after a few years, the general populace is confused and think it's just another Transformers movie they are sick of seeing over and over again, and the mixed signals from producers saying stuff like "it's not a reboot", when the movie clearly is and erases much of the stuff in the other movies.
Hasbro started their film group and want their hasbroverse to happen hard. If it makes some profit, they probably will push through with more eventually. Don't think they have another TF movie on their slate planned for a couple years right now even yet so if anything they give it some space to cool off. GI Joe: Snake Eyes entered production and their other yet not named projects, they are gonna try I imagine to keep these things going and tie them together eventually.
Hasbro also is all about selling toys, and their new investment in film is to push these movies and sell merch. Not only toys, but Hasbro has now stated they are an IP company, so licensing and making money from alternative means is a big factor for them as toy sales have declined in past years. From TF sites, Hasbro is going all out on the merch bonanza, especially overseas. In China they are going in hard on TF toys too
