Thanks for all the info and links I'll give them a deeper read when i have some time

"Do any lite clients randomly query full nodes for random transactions (ie, random regions of blockspace)? This would help user to “deny” that they actually own any of the coins they are asking about. In fact, the mere presence of this option may be sufficient to give considerable “deniability”. It needs only to be on by default"

This method for plausible deniability when using lite clients caught my eye. Really good idea. Don't know why this isn't enabled by default for all lite clients.
