The only thing that shouldn’t be done is to daven Mincha and Ma’ariv both between plag and shkia:- …….. However, if this is going to pause problems, 2 options:-
1) If praying with a Minyan, there are Kulos for “Tartei dSasra” in light of “Tircha dTzibur” which you or/& your local Rabbi may decide to rely upon;
2) There is also an option of calculating daytime seasonal hours, based on:- from daybreak [A.K.A. Alos haShachar] thru nitefall [A.K.A. Tzeis haKochavim] which may cause Plag haMincha to be at a more convenient time, with your busy schedule. BTW in some very Northern countries at the height of winter, this later Plag haMincha could come out after Shkiah, if day is extremely short, and “Bein haShemoshos” is very protracted; Needless to say, in such a situation, one must utilize Plag haMincha based on day from sunrise thru sunset.
