ST KILDA is yet to settle on its forward set-up for Saturday night's clash with Melbourne, with former West Coast utility Beau Wilkes being considered as a late call-up.

The Saints have lost Justin Koschitzke (suspended) who was found guilty of striking former teammate Zac Dawson in last week's loss to Fremantle, but have brought back Jason Gram for his first game of the season after a hamstring problem.

Wilkes was named best on ground for VFL team Sandringham last week and has been named an emergency against the Demons.

Saints coach Scott Watters said he was still open to the idea of bringing Wilkes in.

"In our squad of 25 we've got the potential to bring in Beau Wilkes if we choose to, or we can play slightly smaller," Watters said.

"We still think with Nick [Riewoldt] and Rhys [Stanley] we've got two quality tall targets that can provide the structure we want. We'll probably make that call closer to the game."

Watters admitted weather could play a part in the final selection decision, with late showers forecast for Saturday.

Whoever is selected to play forward, Watters is hopeful they can take their chances in front of goal after admitting conversion was the main problem in the loss to Fremantle.

The Saints had several opportunities in the final quarter last week but squandered them.

"We felt we had enough of the ball inside our forward 50 and inside our front half to win the game. It's interesting because in the three weeks prior to that, our conversion has been very good," Watters said.

"It's not like we need to completely reinvent the wheel but there were missed opportunities last week."

Watters is plotting against fellow first-year coach Mark Neeld. The pair worked together as assistants under Mick Malthouse at Collingwood, and while keen to downplay any direct competition between the pair, he admitted they had a decent understanding of each others' football philosophy.

"He'll have expectations on what he thinks I bring to the table and vice-versa ... But you've got to be careful about that because it is really easy to change that as a coach," he said.

"You plan for a lot of different contingencies. It's already clearly evident the type of footy Mark wants to play, the contested brand of footy and looking for territory wherever possible. That has been evident in five to six months and certainly in the four weeks of this season."
