So if its possible can SO do it please

i cant im not good into modding (just using and endorsing

but it could be quite easy if there is ondeath event attached to npc/creature and that event could trigger script that simply use xpReward function but i do not know how to do this.
giving xp myself is not what i want . i thing that xp formula would be good and fair. i use 2.5x slower leveling along with many hardcoe mods and few my own ( but that are simple changing fixed game settings not dynamic one.
I don't mod myself. But I like using the console to give my self xp, then I can give what I think is an appropriate reward. For example if I kill a bunch of death claws from 1000 feet away undercover of night, I won't give myself anything extra. But if I went in close and run and gun them, wasting stimpacks, using vats,etc(perhaps dieing a few times) then I will give myself some extra xp. Same for quest rewards that are too small or random actions that I think deserve it. I also use the console for other reason to help improve the game for me, like I think the prices are too low at the NV med clinic, so I just double the cost of all the operations. So before say getting the STR implant which normally cost 4,000 caps, I wait till I have at least 8,000 caps then go there use the console to get rid of 4000cap, then do the operation, so I am out 8000 caps.
Also one time I had some random companion for a quest(1 time companion) I could not give them a stimpak and the were killable. So I just use the console to get them back to full health when low and then drop a 2-3 stimpaks on the ground.
Its the same with fast travel I use only when the game crashs to get back were I was headed, I enjoy running from place to place. I find you can make the game alot more enjoyable do these kinds of things.
And for those that say well I don't have the self control to do that, then is it really more enjoyable for you then? I follow my "rules" because there fun, otherwise I would not bother, there is no self control issue because I am having a better time, if using fast travel more increase the amount of fun I was having then I would do it, and now and then once I reach like 100 hours of playtime I start to, just now and then though.
