nice harvest my friend, well done looks and sounds very nice,
now for the grafting, ill be giving it a try myself in a day or 2, just make sure you got a good guide so you know the best place to have the V cut at the node, then you need to make sure its sealed so air dont get in then it should take,
anyways not sure where you got the indica sativa info from, both indica and sativa have hollow main stems, if the side branches get thick enough then their also both hollow, its not the hollow part you need to graft though, you want a nice side branch as cutting and place this into a branch at a node that has the same stem width, that is what ive read and what ill be trying,
but indicas are hollow, i know as i was tempted to start injecting something inside the plants to give them a boost but never got round to testing that, but my sativas main stems are hollow and side branches are not if their not hunky, the same with indica, main stem is hollow, the bigger the stem the bigger the tube in the middle, so skinny plants wouldnt be hollow but both sativa and indica have hollow stems on the main trunk part and big side branches, so it should be possible to graft any plant to any plant,
i was at my moms the other day and she has got a tree thats been grafted in her back gardern, she has lived their for 30 years so its been grafted long before she moved in, anyways she has got an apple tree with 1 trunk, but one side of the tree gives cooking apples and the other side gives very nice sweet eating apples, so i guess any plant can be grafted,
ill keep my fingers crossed for you, what i might try is grafting using rizzla so it creates a tight seal then use tap to prevent light getting in, then another graft im going to attach to the stem and then use honey on the outside to create a seal before using rizzla or tap to keep it free from problems,
as long as the graft is fully touching all the way around then it should be ok, it needs to be a nice tight seal so the V needs to be the same size, the cutting needs a same size V as the V you cut into the parent plant, now would it be best to have a very short V with a sharp angle, or would a longer V be the bets option so you have more surface area touching, ill try both when i try mine, we know it works so with a bit of practice it should be possible,
give it a try and see what happens, im sure an indica and sativa will take as they both have hollow stems

Now the next step would be to have two multistrained grafted plants to produce seeds, and see what genetics comes out of that! Interesting!
Ideal...the way i would do it is graft a male to a female..or vice a versa 
..and let the plant seed itself..hey..i'l put three females on a male plant...and i got a lot of bagseed to work with...got a head magnifier so i can get that cambrem...however you say it..get it lined up..i'm ready to go..
