Hi, Jim!
Here are my "2-pennies' worth":
In such a small scale, 20mm or 1/96, or 1/87, i.e. the American "HO" model railroad scale, or British "OO" model railroad scale, the height-differences in the figures' size, visually-speaking, are going to be very minimal...
Also, and this is important to many figure-modelers, ESPECIALLY in the larger scales, one should take into account that most humans were quite a bit shorter in our earlier historical times, right on up to the middle of the 20th Century. Of course, there were some "6-footers" around, but they were a distinct minority in comparison to the rest of the human population.
I don't know for certain, but I think you MAY have some luck with the US-based AMERICAN SHIPWAYS, which specializes in all types of ship models and ship-detailing supplies. Sorry, I don't have a link for you at the moment, but you should be able to find them via GOOGLE.
In addition, I believe you MAY find that EDUARD Model Accessories may be able to fill your needs in small-scale Naval Personnel; these are made of photo-etch and are pre-painted, but unfortunately they are only two-dimensional. Again, in such a small scale, that may not be so noticeable. I'm pretty sure that EDUARD manufactures 1/350 and 1/200 scale Naval Personnel, but "I'm at Sea", (

) in regards to the larger scales which you happen to be working with. It's worth a try, at least...
You might also try your luck on Ebay for any of the above- There are literally thousands of hobby-suppliers that list a veritable GALAXY of different products on Ebay...
No, I do NOT work for Ebay,
Admittedly, I do A LOT of shopping on that site. For example, I just bought a case of (6) O.E.M (Original Equipment Manufacture) Engine Oil Filters on Ebay for $45.00 USD with FREE Shipping. That's a pretty darned-good price for those particular Oil Filters. That's $7.50 USD per Filter, which VOLKSWAGEN usually charges at LEAST $12.00-$15.00 EACH for the exact same Filter, depending on where one wants to get "ripped-off"... I'm VERY particular when it comes to buying stuff for my car. She only gets CASTROL Full Synthetic Engine Oil, and 91-93 Octane Premiunm Fuel, too... (Turbo-Engine, you see..)

Good Luck in your searches and let us know how you've fared...
