Hmm, Galadhrim could look cool alongside Numenoreans. But yeah, as whafrog says, they're a hard army to collect due to the amount of metal. You can throw the weaker Numenoreans in the rank and file if you want and use the Elves as a hard hitting elite force but you'll still want Elven numbers to maximise the numbers of your Elven Archers. On the plus side though, Numenoreans shouldn't be too hard to give a spear too in exchange for their sword. But I think the key will be to choose one of the major heroes to build your force around (2 if you don't want many warriors) and the rest captains.
An example (based on what you have - you'd just need to buy the Numenorean Bows and one more lot of Elven Spears) would be:
Elendil (with shield)
8 Numenoreans (shields and spears)
3 Numenoreans (bows)
Elven Captain (with HA and shield)
6 Elven Warriors (HA, shields, spears)
4 Elven Warriors (HA, elven blades)
Elven Captain (with HA and elf bow)
6 Elven Warriors (HA, elf bows)
Total: 598, 30 models, 10 bows
I chose Elendil for the list because he'll be able to go toe to toe with anything and his free heroic combats will help him actually do some damage. Don't take it as an optimal list, it's just something I threw up quickly. Most people will recommend never taking Elves armed with Elven Blades (as they come with a hand weapon) but rather always giving them shields. Which is all well and good if you can convert/afford it (or are prepared to use Galadhrim models). In general though, you'll probably want to get rid of spears on your front line. For example, discard all the Elven spears and count them as hand weapons and you could buy another Numenorean archer or get rid of the Numenorean spears and buy another Elf (non-archer).
Personally, I prefer using the Heavy Armoured Gondor list to represent Numenor. I mean, thick leather over the top of chainmail counts as HA to me
. And there's much more variety in the list. Rangers = well Rangers/pathfinders/scouts, SKoDA = Elite Knights (iffy due to shortage of horses), CG = elite warriors (also good steel bow representation), GotFC = King's Guard, Avenger/Trebuchet = Siege Equipment (for attacking Mordor, defending forts).
I don't know about others, but I'd be happy to let you combine the Elves and Numenoreans into one list in friendly games for army selection which would definitely help you with bow limits.
