Soul Exchange: Is Silverpaw worth 15 non dupe heroes?

[Raffinho]

Hi, I have a few 5* heroes that I don't have duplicates of, but will probably never or only occasionally level up.

But is a single hero (Silverpaw) worth sacrificing 15 heroes?

The heroes I have to choose from are these 19 guys.
First 3 are no brainer, but who else would you send to SE?

Horghall (dupe)
Richard (dupee)
Marjana (dupe)
Queen of Hearts
Anzogh
Margarete
Bai Yeong
Balbar
Zeilne
Skagremar
Green Knight
Milady de Winter
Lepiota
Camila
Cardinal Richelieu
Louhi
Ares
Elradir
Maple

I will assume they are all at LV1
- Camila, unless you have a costume
- Maple
It may be risky but...
- M. de Winter
- Richelieu
(Because Musketeers are getting costumes)

I am not familiar with the other heroes...

I tend to judge my "keep holding onto or let 'em go" based on how often I see them showing up in defense teams, or if there is a costume on the way that might make them relevant again. At the point, I usually keep the newest and purge the old. Some of those were good in the day, but most aren't going to be worth the mats to take even to 4/80 let alone LB or emblem.

Another thing MAYBE to consider for who to keep is if anyone would be a good addition to your Titan team (e.g. DDown or EDD). 

For what it's worth, I purged several non-dupes for Silverpaw, so I'm definitely biased that he's worth dropping deadweight heros to pick up. A further question would be if there is one more hero you'd part with to hit 20 for SE; there are some REALLY GOOD options at that level.

[Raffinho]

5 more will be difficult. And I'm more into the 15 soul tier, nearly all of them 

All possible souls are at Level 1-1.

Costumes are available for those, but I have non of the costumes. I don't know which could be chosen from the Outfitter.

Queen of hearts
Zeline
Lepiota
Camila
Louhi
Ares

[NevarMaor]

Lepiota is available from outfitter, that's where I got mine.

Checking here: https://empuzzled.com/visiting-outfitter/

Only Camila and Louhi are not available yet.

Note: I have Skargremar maxed but never use him, which says a lot given the sad state of my reds
