I thought I'd remove the upper and lower boom and add those to the front of the main one, but the spacing would be inconsistent.
I was going to do this based on information here using this calculator. Before putting in that much effort, I simply removed one director from a couple front halves and joined two fronts to a complete Stellar Labs 30-2476. This worked well and I abandoned plans to drill.

I suggest you go with a little trial and error before designing from scratch.
