Consolidating Private Keys To Batch Multi ETH Smart Contract Operations Into 1 Transaction?

I have an ERC20 token scattered on multiple ETH wallets.

I have to "bridge" it for an airdrop which costs $300+ per wallet in gas fees.

If I export/import the private keys from all wallets, will I be able to bridge all the wallets in 1 transaction (like Electrum does with BTC)?

Or will this not work with the ETH blockchain architecture?
