Yes 
If the competitive punchy stuff is the no 1 priority then you could consider doing a 2 wk V02 would be a good experiment and might have more an immediate impact. Its lower risk in time commitment and generally works. Then you can consider the longer term planning through a plan builder.
Depends when you completed Build/s if its wise to just do another one straight away or if you had a gap, then maybe you could do a build that is more aligned to your requirements ie Short power build (SPB) and start that. If it was recent perhaps best to do Sweet post base 2 first then SPB or something along those lines with rest in between but you dont necessarily need to do the full 6 wk SSB2 i.e. 3+1rest. Doing base-build now is quite a long cycle and with the summer coming up you sound like working on this area now is probably key
Therefore, If you’ve just finished Build then a specialist plan might be better. i.e RR as this would be very focused on higher power development. Sounds like you have a good base and w/4 years and those miles. The essence of the Specialist plan is to target areas that fit your event/goal which in this case is like a RR or use workouts for inspiration
"The demands of rolling road races are often more wide-ranging than races including long, sustained climbs. Riders face recurrent flurries of attacks & counterattacks in any road race, but when the course undulates with more frequent & shorter climbs, even breakaway riders find themselves exerting widely varied efforts over the course of their races.
So the aim here is to increase Sprint & Anaerobic power in addition to improving power & time at VO2 Max while also maintaining your base, aerobic Endurance fitness."
