Here's one way. Not sure you'll like the gymnastics that it requires:

[x,y]=deal(rand(1,40), rand(1,40));  %scattered input data

scatterCustom(x,y)

function scatterCustom(x,y)

    %%Create marker prototypes
    t=linspace(-pi/2,pi/2,1000)';
    t(end+1)=t(1);
    p=polyshape([cos(t),sin(t)]/35);
    q=rotate(p,180);
    
    
    f=@(zz,xx,yy) arrayfun(@(u,v) translate(zz,u,v),xx,yy); %translator
    
    %%Plot
    plot(f(p,x,y),FaceColor='b');hold on;axis equal
    plot(f(q,x,y),FaceColor='none');hold off

end

Thank you, Matt J. Your code is excellent.

Unfortunately, markers are only customizable between a limited number of pre-set shapes.

You will need to patch(), as I recently described in https://www.mathworks.com/matlabcentral/answers/2164720-how-to-add-pattern-fill-to-markers-in-scatter-plot#answer_1542590

Or I suppose you could use fill()
