Yes, you're right!
On the left there's the Ushiromiya family and the servants, with the half Braviary standing for the Ushiromiya family's crest: the One-winged Eagle. Celebi is ange, skydiving like in EP4.
The wingulls are the big hint for the english title, When The Seagulls Cry.
Steelix are the 10 tons of gold, Lilligant is Beatrice, the Golden Witch (volcaronas are perfect for the golden butterflies). Gaap, virgilia and ronove are haunter/mismagius/empoleon, the kyrlias are the 7 sisters of purgatory since they have similar skirts. Lopunny are the siestas and purrloin is Bernkastel (cat tail and the such). Obviously skitty is lambdadelta (sadly there isn't any cake pokémon. No, vanillite is ice cream).
Well, congratulations, you solved the epitaph, here you go: 10 tons of gold all for you.
