What division are Ipswich in these days? If we're faffin about with loans they need to be from top end Championship clubs at the very least and of a similar quality to Lowe.
Probably more chance of signing Gow than Gauld.
Can't see Stewart coming back - don't imagine he enjoyed his first stint all that much and he's put himself in the shop window again with a good season at Killie.
Someone mentioned Jordan Jones - he's more likely to head down south I'd guess.
