This is a much bigger question than it looks.
Those musks you are talking about are:
a) not made from animals
b) perfumes in their own right made, in some cases at least, to be worn
c) they are in various kinds of carrier oil - some are soluble in ethanol and some are not
So I don't know that that's the best way to go about it. Vanilla is another one that is complex: it's very easy to end up buying something that won't work in alcohol or that will work but only with difficulty.
So, I recommend you have a look at the selection of musks available from Hermitage - all of which are alcohol soluble, mobile liquids, some pure individual musks and some pre-diluted to defined levels. There are other suppliers you can use but be aware that some musks are crystalline solids or otherwise hard to handle so make sure you know what you are buying. I've given some details of some of the more common synthetic musks on my blog that may help.
If you want to use vanilla I'd get that pre-diluted in ethanol too (Hermitage stock that as well) or alternatively make a tincture yourself from vanilla pods (details on another thread here if you search for it).
Then you can add any essential oils you like, in whatever proportions you like to build up a fragrance that will dissolve in ethanol and can be use in a spray. Plan to use it at about 10-20% concentration and you won't be far wrong.
If you do want to use some of those musk oils you listed, I'm afraid you'll have to experiment for yourself to determine whether they will work in ethanol. If they do you'll also have to guess at the concentration - my guess would be about 30% for most good quality oils intended for direct use - which means you'll need to use a lot more than the pure musks.
Finally, will it smell good - if you get the blend right it will - if you keep it fairly simple to start with you should be able to put together something you'll enjoy quite quickly. Then it's a case of practice, practice, practice just like any other art.
