I say do it if you got the $$$$$! You an also chop some of them down later if they get too crowded. Or you can keep pruning it to keep it under a certain height.
For me I'm planting a whole bunch of cherimoya from seeds. so, no cost for me. Some are in 2-3 trees together.
I have a 1,000sq ft house with a small swim pool on 8300sqft lot.
And I got:
-10+ cherimoya trees producing, 20+ will be producing this year or next. And plan to add another 50 seedlings cherimoya.
-30 mango graft trees, 1 only in ground, rest are in pots.
-20+ banana in ground
-several soursop in pots
-several rolina in pots
-10+ citrus in pots
-10+ guava trees
-couple dragonfruit patches
-1 giant lemon tree in ground
-the swim pool is for growing taro, got about 7 pots (10gal) , planning to add maybe another 20+ pots.
few other misc fruit trees
-1 giant palm tree and japnese maple- to me it is useless since it doesn't produce edible fruits
- planning to add some more...
I took advantage of the front yard as well. Along the drive way are pot veggie like Luffa and gourd.
