How to zoom an Ordnance Survey OpenSpace Pro map to make it bigger rather than to show more features

I'm trialling Ordnance Survey OpenSpace Pro WMS, and I have a basic map showing all the layers I'm going to be licensed for (free ones plus vector map local). This works fine, but I'd like to make the most zoomed level of mapping (VML) bigger on the screen if that's possible? i.e. so I can see it more clearly and the location of pins plotted on the screen more clearly. Obviously I'm not expecting any more data features/detail to become visible (as I'm not paying for any more detailed layers of mapping) - I just want to zoom in on the same map tiles more closely.

I'm initialising my map as follows:

var options = {products: ["OV0", "OV1", "OV2", "MSR", "MS", "250KR", "250K", "VMDR", "VMD", "VMLR", "VML"]};

osMap = new OpenSpace.Map('map', options);

Would be grateful to know if this is possible. I'm not a mapping/GIS/OpenLayers expert, so hopefully there's a simple way to do it.

Here's a OS map with max zoom level (showing vector map local). OS Map VML layer - default magnification

Here's the same map but magnified using browser zoom to achieve the affect I want - i.e. the same map layer, but bigger.Magnified OS Map VML layer

I've achieved this using browser zoom which is a fudge and I can't expect my users to do this. I will be plotting points on the map too, so using browser zoom will just make all the point markers massive too. Ideally I want to make the map bigger, and leave the markers, copyright statement, zoom control etc all the same original size.

p.s. This question seems to be similar, but the recommended actions don't seem to be compatible with my situation.
