If a Skimmer is Spiked, do the Spikes become lighter?

[JustQuestin2004 he/him]

Interesting question, if you spiked a Skimmer with something (let's say a Gold Spike cause it'd be heavy), and they stored their weight, would the spike also decrease in weight? Because it counts as part of their body when it comes to Steelpushing right? So would it count to Iron Feruchemy?

[Quantus he/him]

I think so Yes, once they are implanted they'd be considered part of you and so they'd be affected by those internal powers along with you to some degree (probably cant Gold heal one whole since it'd have gotten unplugged from your spiritweb).  They'd also probably be protected from things heat melting with the methods Firesoul's have available, especially for the low melting point metals.

Extra bit, what about implanted Metalminds, would those also count? It might be a way for a Skimmer to avoid being weighed down by their own Ironminds.

I was going to write that spikes aren't part of their body, so they should not decrease in weight but then I looked at this WoB which I had in mind:

Trae Cooper (paraphrased)

Why are Invested objects like metalminds and Hemalurgic spikes able to be Pushed and Pulled on, but Shardblades and Shardplate, which are also invested, are not susceptible to Pushing and Pulling?

Brandon Sanderson (paraphrased)

[...]

2.) Further, Invested objects also gain resistance to pulling/pushing based on proximity to soul possibly via the soul. An example given is that a Hemalurgic spike touches the blood of the person, and from there is now part of both the Spiritual Realm and the Physical Realm. This provides what Brandon termed a kind of "soul interference," based on its proximity to the soul.

This further explains why Vin required more than normal power to Push/Pull the metalminds from the Lord Ruler, because of their proximity to his soul, via the Spiritual Realm.

So spikes can't be pushed because of their proximity to the soul, but that also makes them a part of PR. So maybe? It makes sense their mass would be affected by F-Iron if they really are considered as a part of the Hemalurgist body.

Per this WoB they also have this proximity to the soul so they should count as well.
