Been HCRV for 2-3 weeks (clarification questions)

This is my first post, though I've been reading the forum for a few weeks.  I've been eating 100% raw fruits and vegetables for 2.5 weeks now and I love it.  I'm 21 years old. 5' 8'' and about 145lbs I think (haven't weighed myself in a while and I don't have a scale now).  I'm quite lean and have muscle that I've built over the last couple years on high protein diets.  I'm trying to continue to build muscle and gain weight on this diet.

Over the last week I've found a pattern with eating.  Here is basically what I've been doing:

Breakfast (8am): 1500cals.  2 Mangos, anywhere from 7-10 bananas and then however many dates to get to 1500 calories.

Lunch (noon): 1500cals. Usually 1-2 pieces of juicy fruit like nectarines or pears. 9-10 bananas and the rest from dates.

Dinner (6-8):  I make sure to get lots of calories in during the day, and use the evening to eat more of the juicy fruits that I can't get enough calories from like watermelon, kiwis, strawberries, grapes, or oranges.  After that, I have a salad with lettuce and/or spinach, peppers, cucumber, tomato and I eat half and avocado.

My end of the day stats are usually the following:

calories: 4000

protein: 50-55g (4-5%)

carbs: 88%

fat: 30g (7%)

My questions are the following:

1)Overall, how does this eating pattern look?  More specifically, if I'm trying to build muscle, how many calories should I aim for?  Is this sufficient?  I could easily just eat more bananas and dates in the evening to crank it up close to 5000, but I usually have had enough of them and I want to enjoy variety with juicy fruits for dinner or I'll get sick of this diet.  But if it's necessary, I'll substitute some of the high volume, low calorie juicy fruit with some more bananas and dates.  

2) I eat the half avocado with my salad because it fits my fat intake and I love it.  I know 80/10/10 are the upper/lower bounds, but seeing as I'm trying to build muscle, I'd like to get as close to the 10% protein as I can.  However, eating just fruits and vegetables, I can't seem to get to 10%  What are possible ways to get there?  Are there higher protein fruits I'm not eating?  Is it recommended to eat nuts and seeds, particularly hemp seeds?  I know they are also fatty, and would eating nuts and seeds affect the benefits of eating only raw fruits and vegetables?  

Any comments, suggestions and advice would be much appreciated.

Thanks,
