Quadrameter, Amos? Come on, you can squeeze out just a little more and make it pentamenter.

Or...would you like to try for troachic heptameter, the hepcat's scansion?

Oh, wait, I knnow! Something like this:

Hwæt! We Gardena         in geardagum,
    þeodcyninga,         þrym gefrunon,
    hu ða æþelingas         ellen fremedon.
    Oft Scyld Scefing         sceaþena þreatum,

    monegum mægþum,         meodosetla ofteah,
    egsode eorlas.         Syððan ærest wearð
    feasceaft funden,         he þæs frofre gebad,
    weox under wolcnum,         weorðmyndum þah,
    oðþæt him æghwylc         þara ymbsittendra

    ofer hronrade         hyran scolde,
    gomban gyldan.         þæt wæs god cyning!
    ðæm eafera wæs         æfter cenned,
    geong in geardum,         þone god sende
    folce to frofre;         fyrenðearfe ongeat

    þe hie ær drugon         aldorlease
    lange hwile.         Him þæs liffrea,
    wuldres wealdend,         woroldare forgeaf;
    Beowulf wæs breme         (blæd wide sprang),
    Scyldes eafera         Scedelandum in.

Sure, it's a little bit more complex, but I'm certain you can do it.
