The Morton boss has also offered one-year contracts to Slovakian defenders Michal Habai and Tomas Peciar after the pair's impressive performances against Sheffield United and Well.
Moore has revealed that the trio have all agreed terms in principle but also admitted there are finer details that will have to be ironed out before the deals can be sealed.
Cham - born in Belgium, and not Holland as originally thought - opened the scoring on 16 minutes, rounding Lee Hollis after fastening onto Peciar's intelligent, angled pass.
He added a second eight minutes later, showing impressive strength as he battled to get on the end of Jonathan Page's deflected cross before forcing the ball home from close range.
By half-time the Ton management team had already seen enough and replaced the former KV Mechelen and VV Sint-Truiden youth player with Tony Wallace.
Other trialists on show at Cappielow included Marc Fitzpatrick, David Crawford, Sam Cox, Dale Fulton, Martin Murphy, Ryan Clark - an Australian right midfielder - and Habai.
In the second half, Fraser Kerr pulled one back for the visitors, who started ex-Ton defender Craig Reid at right-back, when he headed in a Paul Lawson corner on 65 minutes.
But Murphy, a 22-year-old Scot who until recently was playing college football in the USA, wrapped up the win with a wonderful chip from 25 yards seven minutes from time.
Moore told the Tele: "We're hoping to get a contract sorted with the Belgian striker by the end of the week. He's agreed terms and there are just a couple of things to be ironed out.
"He's a big boy and I think he can give us a bit of the presence up there that we've lost since Peter Weatherson left. That could benefit wee Archie Campbell playing alongside him.
"He's only young - he's 20 - so we're hoping to get him on a two-year deal. It's a wee gamble, but it's a gamble worth taking. He could be a gem.
"Myself, Mark [McNally] and David Hopkin looked at him and thought, 'Where are we going to get someone like that over here in Scotland?'
"We watched him for 45 minutes, he scored a couple of goals and he showed all the attributes we were looking for in a striker.
"He held the ball up well, he was strong, he was physical, he had a wee bit of pace about him, and he was technically good.
"We've also agreed one-year deals in principle with two of the Slovakian boys, Tomas Peciar and Michal Habai, but those are also subject to a couple of finer details being finalised." On the third Slovakian, 19-year-old attacking midfielder Tomas Kamenca, he added: "It turns out we can't do anything with the young boy Tomas just now.
"He's going to have to go back and speak to his club over in Slovakia [FC Petrzalka]. They might want a development fee, which we're not willing to pay.
"So he's going to go back over on Tuesday and try and work something out with them."
